SPECIFICATION forming part of Letters Patent No. 409,637, dated August20, 1889.

Application ned April 2s, 1889.

To @ZZ whom it may concern,.-

Be it known that I, CHARLES W. GLIDDEN, of Lynn, county of Essex, Stateof Massachusetts, have invented an Improvement in Heel- 5 NailingMachines, of which the following description, in connection with theaccompanying drawings, is a speciiication, like letters on the drawingsrepresenting like parts.

In the manufacture of that class of shoe to having what is known asspring-heel it has been found difficult to correctly drive the nailsinto the shoe at the heel because of variations in the thickness of theheel due to inequality of thickness, or to taper, or both, of I5 thelift inserted between the end of the sole and the upper lying next theheel of the last. To obviate this trouble, I have mounted the nail-boxand driver-plate upon a rocking or tipping seat, so that the nail-box isfree to tip 2o in a direction of the length of the sole, to therebyenable the top plate of the nail-box to adapt itself to and lie properlyagainst the heel-end of the sole in which the nails are to be driven.

My invention consists, essentially, in the combination with a nailbox,drivers and driver-plate, and a convexed support, of a block having acon'vexed seat forthe support, whereby the said nail-box, drivers, anddriver- 3o plate may tip to enable the top plate of the nail-box toadapt itself to the holes into which the nails are to be driven. y

Figure l is a top or plan view of a nail-box and its support embodyingmy invention; Fig. 2, a section of the parts shown in Fig, l on the linea', and Fig. 3 a section on the line The block A has a central portionprovided with a concaved seat a, (see Fig. 3,) on which is mounted aconvexed support Z1, having the 4o driver-plate c attached to its upperside by suitable rivets or screws 2, and free to tip, as required. Thesupport, as well as the driverplate, is provided with a central opening,through which is extended loosely the usual rod d, upon the upper end ofwhich is secured the nail-box (Z, provided at its upper side with a topplate having holes into which are loaded the nails to be driven into theheel, the said holes also receiving the drivers d3. The

5o block A is provided with an enlarged opening Serial No. 308,303. (Nomodel.)

w about the rod CZ, so that the support may tip without the rod strikingthe block. The top plate cl2 (shown as concaved to conform to the4rounded or molded heel part of the sole) is supposed to be detachableor changeable for one of another size or with the nail-holes arranged ina different curve, the said top plate being shown as held in place atone end by a bridge-piece d6, through which and into the nail-boxareextended screws 4.

It will be noticed that part of the driver plate upon which rests thelower ends of the drivers d3 is inclined to thus enable the drivers tobe placed in inclined position and drive the nails into the heel at aninclination. The concaved seat formed in the raised part of the block Ais shown as extended sufficiently to leave concaved grooves, and thesupport Z9, entering the said groove, is convexed at its lower side andflanged to rock on the seat a 7o in the block, the said iianges fittingthe said grooves, such flanges and grooves preventing t-he support frombeing lifted vertically from its bearing upon the seat, the gist of myinvention lying in so constructing the support and block as to leave aconvex surface in one to co-operate with a concaved portion of theother, so that the support, together with the nail-box and top plate,may rock or tip freely in the direction of the length of the sole or SoI heel part thereof to adapt the top plate to any variations inthickness of a spring-heelrlhe apparatus as so far described is adaptedto rock or tip in the direction of the length of the sole; but itsometimes happens with the devices described and on particular classesof stock that it is desirable to compress one part of the heel more thanthe other part to thus shape the bottom of the heel; and to do this Ihave provided the block A with a tapped or 9o threaded hole, in which Imay place a setserew, as t, it constituting a locking device, which maybe turned in against the support when it is desired to conform theconvexed foot or bottom thereof rigidly in place on the said block, andso as to press on the heel harder at one portion of its length than atanother portion. The convexed flanges are shown as extended laterallyfrom the convexed bottom of the support and entering roo nail-box andconvexed tipping-support, coinbined with a locking device to X Jchesupport in adjusted position, substantially as described.

In testimony whereof I have sign ed my name to this specification in thepresence of two subscribing Witnesses.-
